Uniformly-bounded nonlinear networked control systems with uniform quantizer
具有均匀量化器的非线性网络控制系统的一致有界性

A nonlinear networked control systems (NCS) with continuous plant and a time-delay shorter than one sampling period is described by a continuous model. This continuous model is transformed into a discrete one by using the methods of linearization and discretization. A sufficient condition of stability for the transformed NCS is derived by using Lyapunov method and linear matrix inequality approach. A state feedback controller is designed for ensuring the NCS with uniform quantizer to be uniformly bounded. By adjusting the quantization error range, states of the system can be controlled to stay within a finite range, and the quantized level and the code length can be determined accordingly. The Matlab simulation of an example is given to illustrate the effectiveness of the proposed method. Meanwhile, the effect of the quantized error is analyzed.
